I have checked original air dates for all episodes on Магнитогорский металл web archive and our order seems to be correct.

Only episodes I didn't find at all are E17 (Битва за Кавказ) and E18 (Партизаны), so I have nulled and unlocked their air dates as unconfirmed. I have also unlocked "known" air dates for E9 (Агентурная разведка), E10 (Война на море), E12 (Битва за Германию) and E14 (Ржев), which I didn't find under their episode name, but only as general "Великая война", so I can't consider them as definitely confirmed.

General episode order is imo correct though, so it will stay locked as well as episode names. The final episode order is already added as the custom episode group, so there is no need to change that either.

It would be great if you could find some other primary archive source for missing/unconfirmed episode air dates (the unlocked ones). Unfortunately wikipedia is only good to get general information, but for real air dates we need something more reliable, like old TV guides I used. Until then I'm closing this topic. Thanks.

@talestalker All the air dates, especially the ones that were locked, came from the official website and/or archived TV guides. https://web.archive.org/web/20120508005903/http://www.1tv.ru/public/pi=23032 :/

Strange, E8-13 were wrong by 1 day and I had to correct them (now they correspond with your source) and on 2014-05-08 there was "Битва за Берлин" (E8) instead of "Битва за Кавказ" (E17), so I have removed air date from E17 (source PDF). But maybe there is error in the TV guide.

Anyway I have locked E9,10,12,14 again. Only for E17-18 I don't know what air date to use, as I didn't find it in Магнитогорский металл at all...

Why do you use sources that do not contain complete data? I'm urge you to look at screen shot from official trailer- ListOfEpisodes. You can make sure that this series has a division into two seasons(blocks) on this video: Trailer(you will not need to watch the full two-minute video, because I have specified the starting position in this URL)

@TonyMontana79 I have already seen your source, but it only contains information about final episode order which is correctly entered in this custom episode group.

1/ As for the main episode order, we always use original air dates, which your source doesn't contain. Also, we always need to check primary source, i.e official sites and archive TV guides. Indeed, these sources often are not complete (e.g. you can get archive TV guide just for some period of time - in our case we don't know for sure what the original air date of E17-18 was), but the data they contain are most reliable.

2/ As for the eventual season split of this series to 2-3 seasons - unfortunately I'm not able to deal with such problem (for me the series/season split is by far the most difficult problem to tackle even for the series that comes from my home country). For this series it was already settled by @Banana who put all episodes into 1 season, most likely because it is/was in such manner represented in official sources (archive website of original broadcaster).

"most likely" it is a bad word, because Banana didn't give me details about the original source to solve the discrepancy with this TVshow. Btw nice doing business with you! Have a nice day.

It has to be the day the episodes actually aired. 8 мая в 0.15 = May 9; 10 мая в 0.00 = May 11; 11 мая в 0.00 = May 12

and on 2014-05-08 there was "Битва за Берлин" (E8) instead of "Битва за Кавказ" (E17), so I have removed air date from E17 (source PDF). But maybe there is error in the TV guide.

I'll try to find the PDF that I used, but the titles are close enough that I think that one might be my mistake.

because Banana didn't give me details about the original source

It's the first thing I did.

I have originally converted the dates from Магнитогорский металл from UTC+5 (Magnitogorsk) to UTC+3 (Moscow), but according to your web archive link, the times in Магнитогорский металл actually corresponds with the general time as used by Channel 1, so yeah, you are right!

Yes this is was first but after that i'm pointing you on official trailer there is other sequence of episodes! And you gave me the URL [which does not contain a list of episodes at all]. Anyway, i think you guys know what you do, and my support request may be closed. Thank you!
